  • Is the problem with the power cable length only on the DC side, the motor side, or both?

    Am I reading that wing area right? 48dm² (744in²) seems very small, if root chord is (at a guess) 30cm (11.8"), tip chord is 20cm (7.8") and span is 300cm (118") then the area should be at least 75dm² (1162in²)...

  • Surprised no one has made a shadow model yet.  I hate that flying diesel lawn mower.

    @b nevins;  Right about the power leads, and as we all know, long power cables lead to ESC feedback and failure!

  • Well, I guess we'll find out.  I know somebody on the Arduplane team has ordered one.  I for one really hope it works out.  Maybe this one will fly better because it's bigger?

    For myself, even if it flew really well, I wonder if it's just too big to be practical?  Depending on the stall speed, I'm not sure I could even use it at my club field.  And forget catapult launches and parachute recoveries.  I also wonder if due to the size of the thing, maybe it would be better off with a fuel powered engine?  It just seems so big for electric. 

    I'd also hate to have this thing crash in a populated area.  A Skywalker or X8 is one thing, but this could really do some damage.

    Its funny how so many people new to the community say they want a Predator model.  

    I suppose its the romantic poster child of the drone world.

    No-one thinks about the fact that with the narrow wing chord and relatively short body and short tail, its a stall waiting to happen!

    If you get this beauty off the ground, odds are it 'aint coming down in one piece!

  • It will require some long power leads to balance with the motor that far back.  Hopefully this version doesn't have the wing flapping issue that makes the 74" version look like a pterodactyl.

  • Here is the link to buy it: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=...

    $283.29 it is not a bad deal.

  • I liked how he tried to dance around, but touch slight base on the military aspect of it, but he didn't want to drive it home to hard. I like it. But as others have mentioned, I too am wondering about the flight characteristics.

  • @Euan:

    There's a payload bay above the wing roots - especially for heavy stuff like batteries :). Check the product description :).

    And about the color... It's fiberglass... Go buy a couple of spraycans in pink if you please :D.
